Abstract

Potassium titanate fine particles wherein the length is shorter than 5 μm, the content of the particles having the ratio of the length to the breadth is less than 3 is from 70 to 100% by number ratio, the diffraction intensity in the X-ray diffraction is low and the particles are low crystallinity, and the specific surface area thereof is from 20 to 50 m 2 /g.

Claims

exact text as granted — not AI-modified
What is claimed is:  
     
       1. Potassium titanate fine particles comprising the particles having the length of shorter than 5 μm and the content of the fine particles having the ratio of the length to the breadth of less than 3 is from 70% to 100% by particle number. 
     
     
       2. The potassium titanate fine particles according to  claim 1  wherein the specific surface area thereof is from 20 to 50 m 2 /g. 
     
     
       3. The potassium titanate fine particles according to  claim 1  wherein the diffraction intensity in the X-ray diffraction of the particles is low and the particles are low crystallinity.
